Method of producing cyanamide from caloium cyanamde



dilute solution obtained in the latter operation being preferably fused as solvent in prosecuting the process.

tion practically free from dieyandiamide,

consisting lin gradually supplying calcium cyanamide 'to a Water solution and simultaneously supplying carbon dioxide to such extent that the alkalinity of the solution is maintained -below (l5-normal, and moderately coolingr the reaction mixture so as to maintain a temperature not less than 300 C.

the alkalinity of the solution during the re- '10 action'is maintained below 0.5-n01mal.
